I have a 9 speed and I have to hold it in the granny gear. I got it tuned-up and now I have to hold it in place otherwise it'll go into 2nd automatically. Is this normal? Or is it taking too much cable up? I don't know I'm just guessing. I haven't even tried to fix it. Plus it'll shift later or even on it's own as I'm coming downhill. Like a delayed upshift. I'm going nuts.

Your derailleur may be bent, or the shop didn't tune it right. Take it in again and tell them to take a closer look at it.

It's tough to understand or explain on a forum. If you say you recently got it tuned up, go back to the shop and tell them it's not working properly. My guess is there is too much tension on the cable, and that would be a minor adjustment.

Your cable is too tight.If it's hopping on the gears that's usually what it is.

Sounds like your cable actually loosened up, but again, it's hard to understand your problem online. Get someone who knows how to properly adjust it look at it.

sounds more like the derailuer hanger being bent if a shop says they set it up, take it back get them to check the set up firen get them to trow the derailuer hanger alingment tool on it, sounds like somethingings bent and the shop just didn't take a close enough lok at it.

No I don't, but this is great info. I'm taking it down later this week to the shop. Maybe they can give me a discount cause they messed it up. Thanks for the help.

holy shit nice profile pic vish!!!!!!!!

If the hanger is bent it will usually tick and throw the chain into the spokes.

Some bikes come with really wimpy hangers and some come with tougher ones.

If the downshift are delayed I would also recomend checking the B-adjsut screw. This adjusts how close the top pulley on the deraileur is to the cog. Take off your chain and shift into the highest cog, the top deraileur pulley should be 1/4" from the tip of the teeth on the cogs. Any closer and you will experience delayed downshifting, or even inabilty to downshift, a larger gap reults in sloppy slow shifting. The little screw near the derialuer mounting bolt is the one you need to adjust to fix this.

So I just took apart my bike to travel and now when reinstalling the derailleur my top cog is touching the third from the top cassette. Did my derailleur get damaged when traveling. When using the adjustment tool for be tension it is no where near touching the normal area when adjusting the b limit screw. Is there something I'm missing to fix this

Most likely you did not install the derailleur correctly.
Remove and reinstall, paying close attention to how the derailleur gets indexed to the derailleur hanger.
